I had a spare BB400 lying around and some McR16's and 17's so I decided to try making a Cree Sandwich. It was a very worthwhile effort. The BB400 with the P4 Cree easily outshines a BB400 with an SWOH. To keep the Cree from shorting out through the bottom pads, you must grind off the corners of the ceramic. Do it carefully and you will eventually expose the via which connects the bottom pads.
Here it is in a M@g 2AA host
Some shots of the sandwich
Obligatory white wall shot. Cree on left, SWOH on the right. Both LED's driven with BB400's
The red nail polish is for added insulation against shorts against the body. This turned out to be unnecessary in the end though if you're careful about your build.
Enjoy.
